[protege-discussion] GraphWidget with Protégé 3.4.8

because of this thread, I stumbled upon the GraphWidget for the very first time.
That is a very nice widget!

The documentation under is not complete, as some of the images are missing.
Furthermore, I struggle with Step 7: It is not possible to change the allowed class type of the :FROM and :TO because these slots are "read-only". I wonder why..

Hello Jean-Louis,

The GraphWidget will only appear as an option in the "Selected Widget Type" combo box on the Forms tab if you've selected a slot in the Form Editor that has a value type of Instance and multiple cardinality.  In the newspaper example that comes with Protege 3.4.8, the GraphWidget is assigned to the "employees" slot.  If you examine this slot on the Slots tab, you can see that is has a value type of Instance and multiple cardinality.

There is a graph widget tutorial on our website that you might find helpful:
